Abstract
The utility model provides a weather box for detecting the release amount of formaldehyde, which comprises an outer cabin, a heat-insulating material, an outer sealing door, an inner cabin and an inner sealing door, wherein the inner cabin is sealed in the outer cabin, and two independent airflow systems are formed at the inner side and the outer side of the inner cabin; a temperature-controlled circulating fan, a temperature sensor, a heater and a refrigerator are arranged in the outer cabin and outside the inner cabin; and a stirring fan and a wind guiding plate are arranged in the inner cabin. All the temperature-controlled circulating fan, the temperature sensor, the heater, the refrigerator and the stirring fan are controlled by a controller outside the outer cabin. A temperature and humidity sensor is arranged in the inner cabin and controlled by the controller outside the outer cabin, a formaldehyde sensor is connected with a detector outside the outer cabin, and an air jetting device is connected with a humidity gas generator outside the outer cabin through a pipeline. The inner cabin of the utility model is sealed in the outer cabin, so that the inner cabin is in a constant-temperature area, and the air jetting device and the stirring fan of the inner cabin can fully ensure the uniformity and the constancy of temperature and humidity, thereby the reliability of testing results is ensured.
Description
Technical field
The utility model relates to a kind of device that detects the gas burst size, especially a kind of climate box that is used to detect burst size of methanal.
Background technology
At present, in order to protect environment, use organic class or complex class material in a large number, as adhesive; coating, wood-based plate, artificial marbles etc. all have VOC to exist in these materials; comprise the benzene class, aldehyde, ketone etc., wherein formaldehyde particularly is the most serious to the health effect of human body.Measure the content of VOC in the solid body, generally adopt dynamic burst size method of testing.This measuring technology is usually used in simulating under certain indoor environment, and the volatile organic matter release phenomenon of ornament materials or furniture etc. carries out gaseous state sampling and the research that performs an analysis, i.e. growth cabinet method.The measured object sample is put in the climate box, in case constant temperature, constant humidity, constant voltage, permanent gas flow rate, fix time and decide and carry out under the condition of gas flow.If temperature, moisture distribution inequality in the case, the data of measuring just have error, have so just influenced the comparativity and the confidence level of test result.The temperature of growth cabinet, the control accuracy of humidity directly influence accuracy of detection.
The utility model content
The purpose of this utility model is to provide a kind of can keep warm in the case, moisture distribution is even, constant, and burst size of methanal detects the climate box of usefulness.
The technical solution of the utility model is: a kind of climate box that detects burst size of methanal, comprise stainless outer cabin, insulation material, the external seal door, cabin in stainless, interior hermatic door, wherein insulation material sticks on the inwall in outer cabin, interior cabin is sealed in the outer cabin, constitutes independently two air flow systems in the medial and lateral in interior cabin; Outside in the cabin, the interior temperature control circulating fan that is provided with out of my cabin, temperature sensor, heater and refrigerator; In interior cabin, be provided with and stir blower fan and wind deflector.
Described temperature control circulating fan, temperature sensor, heater and refrigerator, and stir blower fan and all control with outer controller out of my cabin.
Be provided with Temperature Humidity Sensor in described in the cabin and be connected with outer controller out of my cabin, the formaldehyde sensor of setting is connected with out of my cabin detector outward.
Being provided with air jet system in described in the cabin is connected with outer humidity gas generator out of my cabin by pipeline.
The structure that the utility model adopts is that interior cabin is sealed in the outer cabin, and the cabin is in the constant temperature zone in making, and the air jet system in interior cabin, stirring blower fan can fully guarantee all even constant of temperature, humidity, thereby guarantee reliability of testing result.
Description of drawings
Fig. 1 is the utility model structural representation;
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As Fig. 1, a kind of climate box that detects burst size of methanal that the utility model provides, comprise stainless outer cabin 1, insulation material 3, external seal door 2, stainless interior cabin 4, interior hermatic door 5, wherein insulation material 3 sticks on the inwall in outer cabin 1, and interior cabin 4 is sealed in the outer cabin 1, constitutes independently two air flow systems in the medial and lateral in interior cabin 4; In the cabin 1, interior cabin 4 is outside equipped with temperature control circulating fan 6 outside, temperature sensor 14, and heater 7 and refrigerator 8, and all be connected with outer cabin 1 controller outward; In interior cabin 4, be provided with and stir blower fan 9 and wind deflector 10, stirring blower fan 9 is connected with outer cabin 1 controller outward, the Temperature Humidity Sensor 11 that is provided with also is connected with the outer controller in outer cabin 1, the formaldehyde sensor 12 that is provided with is connected with outer cabin 1 detector outward, the air jet system 13 that is provided with, it is connected with outer cabin 1 humidity gas generator outward by pipeline.
During work, specimen is put on the brace table in cabin 4, close hatch door, start-up control device, temperature and indoor temperature in temperature controller detects in the cabin 4, determine the temperature state of a control, according to the parameter of temperature sensor 14, select heater 7 or refrigerator 8 work again, cabin 4 was in the constant temperature zone of setting in temperature control circulating fan 6 made, air jet system adds steam in the 13 inside cabins 4, temperature, humidity equilibrium in stirring blower fan 9 and wind deflector 10 make in the cabin 4.When reaching setup parameter, formaldehyde sensor 12 transmits signal to detector, and the conversion back directly shows on the computer monitor of dedicated program, preserves these data and is the burst size of methanal concentration value, so far detects and finishes.
The climate box of the detection burst size of methanal that the utility model provides, entire work process is all by computer operating, and is easy to use, the accuracy of detection height, energy resource consumption is low.
Certainly; the utility model also can have other various embodiments; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
